Tag application

To-do list apps are lame. Why? Because managing the system–learning how to input items, strike them out, sync them, tag them–is often more complicated than low-tech methods like writing something on a Post-it. But people still keep inventing them.

The latest, an iPhone app called Clear, is at least interesting for what it doesn’t do. It doesn’t sync. It doesn’t tag. It doesn’t “intelligently” sort anything. It also doesn’t have any obvious clues in its gestural interface for how to actually use the thing. Is this bad design, or the future of UIs?
